Here's one where the pilot claimed to the NTSB that his dog unlatched the canopy, causing the aircraft to land short of the runway. I witnessed this particular accident from the run-up area and was the first person on the scene, the pilot told ME that he had unlatched the canopy to clear some condensation and neglected to latch it before takeoff.

When I fly with my dog (Husky, ~55 lbs) she wears a chest harness, and is tethered to the baggage tie-down so that she cannot reach the front seats. She mostly sleeps, but wakes up as soon as we reduce power for descent/landing.
